theoretical data retention time is more than 10 years! 4features: ds real time clock module dallas ds is the company launched trickle charge the clock chip, which contains a real-time clock / calendar and 31 bytes of static ram, via a simple serial interface to communicate with the microcontrollerc51 mcu p0 port requires pull-up resistor, if your device does not have a pull-up resistor can be connected to other ports data lines package included: 100% brand new 1/2 x ds module 1/2 x cr batterybackup battery is genuine celestial cr, voltage 3v, current 260mah, non-rechargeable batteriesreal-time clock / calendar circuit provides seconds, minutes, hours, days, weeks, months, years of information, the number of days per month and leap year automatically adjust the number of days3cm wiring methods (procedures in order to provide an example, you can access any io port, modify the port definition in the program can be): vcc → +5 v/3pcb single panel, size: 44mm * 23mm * 1vcc and gnd do not reversed, it would burn the chip 2clock / ram read / write data in a byte or up to 31 bytes of character set type communication3v/5v, can be connected with 5v and 3clock operation by am / pm indicator decided to use 24 or 12 hour formatwith four positioning holes, diameter 3crystal khz, japan imported crystal, matching capacitance 6pf, size 2 * 6mm 53v microcontroller 7working temperature: x 2ds is made large 8-pin dip chip, chip below ic socket for easy replacement and swap chips 60v, operating current of less than 300na ¿ read / write clock or ram data transfer mode, there are two single-byte and multi-byte transfer mode transmission character set ¿ 8-pin dip package or an optional 8-pin soic surface mount package under ¿ simple 3-wire interface ¿ vcc = 5v and ttl compatible ¿ optional industrial temperature range of -40 to +85 ¿ dual power tubes used for the main power supply and backup power supply ds real time clock module parameters are as follows: 1module operating voltage compatible 33v gnd → gnd clk → p02 dat → p01 rst → p00 note: 1ds between the microcontroller can simply adopt the way synchronous serial communication port only used three lines: (1) rst reset (2) i / o data lines (3) sclk serial clockds work to maintain low power consumption data and clock information when power is less than 1mw ds key performance indicators: ¿ real-time clock with energy calculations before seconds, minutes, hours, day, week, month, year capacity, as well as the ability to leap year adjustment ¿ serial i / o ports such a way that a minimum number of pins ¿ wide operating voltage range v ¿ 2
